“…The ossified pons supratendineus, the fusion of the astragalus to the tibia, and the smooth surface of the bones indicate that the material comes from an adult individual. The bones were morphologically and biometrically compared with representatives of all extant species of Leptoptilos and Ephippiorhynchus from the Nationaal Natuurhistorisch Museum Naturalis in Leiden (prefix RMNH), the Institut Royal des Sciences Naturelles de Belgique in Brussels (prefix IRSN) and the Natural History Museum in London (prefix NHM) (), including Ephippiorhynchus asiaticus asiaticus (Latham, 1790) (RMNH 106117), Ephippiorhynchus asiaticus (Latham, 1790) (RMNH 5528, IRSN 12385, IRSN 12386, IRSN 12388, IRSN 12389, IRSN 42165, IRSN 42167, IRSN 42249, NHM 1854.4.6.4, NHM 1859.5.29.2), Ephippiorhynchus senegalensis (Shaw, 1800) (NHM 1868.3.21.26), Leptoptilos crumeniferus (Lesson, 1831) (RMNH 5995, RMNH 4334, IRSN 12396, IRSN 17115, IRSN 1711Y, IRSN 41570, IRSN 55844, NHM 1866.12.30.23, NHM S/1952.3.133, NHM S/1952.3.182), Leptoptilos dubius (Gmelin, 1789) (RMNH 106118, IRSN 12394‐95, IRSN 60379, NHM 1851.11.10.53, NHM 1845.1.12.290, NHM S/1952.1.104), and Leptoptilos javanicus (Horsfield, 1821) (RMNH 106120, RMNH 1061119, IRSN 12391‐93, IRSN 18523, IRSN 48289). Because of sexual dimorphism in size, care was taken to include both males and females of each species in the sample.…”
